RESILIENT SUPPORT FOR-TI'RE-CASIKNGS.

Specification of LcttersPatent. Patented Dgo, 14:, -1920 Application filed May 4, 1920; SerialNo. 378,8132

- flo-eliminan@ t 'may concern 1. and State of Kentucky, have invented certain new and useful Improvements in Resilient Supports for Tire-Casings, of which the following isV a specification, reference being had therein tof the accompanying drawing...

My invention relates to improvements in resilient supports for tire casings, and more particularly to supports for use in automobile tire casings.

The object of my invention is to provide a resilient supporting means for pneumatic tire oasings whereby the resiliency of the tire is preserved without the use of an inner tube which is common to such tire casings.

A further lobject of my invention is to provide a resilient supporting means for pneumatic tires which takes the place ofthe usual'` inner tube and thereby obviates punctures and4 blow-outs.-

A further object of my invention is to so construct lmy improvedl resilient supporting means for tire casings that it will support the casingy in its natural contour and at the same time insure easy riding and absorption of bumps and jars. i

'Y A still further object of my invention isto provide an improved resilient supporting means for tire casings which can be applied to the usual wheel and tire casing now found in use.

Other and more specilicobjects will now fully appear in the following specification and claims.

' Referring nowA to thel drawings- Figure 1 is a side view in elevation ofa wheel and the casing, partly broken away and shown in section, showing my improved supporting means as applied to the wheel rim and the tirecasing.`

Fig. 2 is a detached perspective view showing a portion of the spring supported elementl of my invention.

Fig. 3 is a cross-section taken on the line 3-8 of Fig. 1, showing a tire containing my invention.

Fig. l is sectional perspective View showing the position of the wooden blocks when being placed in the tire.

Referring now to the drawings wherein similar characters designate corresponding-parts throughout the several. views, 1

denotes the hub of a wheel, -2 the wheel spokes, 3 the wheel felly and t is the; tire wheel rim which is of the usual type for use with clencher tires, being provided with upwardly projectingV edges 5 for receiving the beaded edgesv 6- of thetire casing 7.

Completely encircling the rim l of the wheel and lying thereon between thebeads 6' of the casingA is wheel-ring 8, comprising a plurality of.' sections 9, hinged as at 10, so as to enable the ring to conform tothe circularV rim, the en'd'secti'ons ofthe ring 8v having uptu'rned ends 11 and 12, which are drawn and fastened together' by a bolt 13.

Bythis construction thewhecl ring canl be made to lit a wheel of any circumference by increasing or decreasing the' number of ring sections and tightening them through the medium' off the boltV 13.

At predetermined' points upon the wheelring 8, preferably one aboveeach' spoke of the wheel, are semi-circular wooden blocks' 14, having their rounded faces 14a fastened transverse the wheel ring by'means'of bolts 15. The fiat'faces of the blocks carry metal plates 15f, which are provided with raised portions 16 to receive the lower ends 17 of the coil springs 18, which support the-semicircularl wooden blocks. 20.

The blocks 2O have fiat' faces carrying the metal plates 21, which areprovided with raised portions 22 to receive the upper ends 23 of their supporting coil springs 18, and carry upontheir rounded faces, by means of the bolts 24, theV metal plate sections 25,

which are substantially semi-circular in the transverse direction of the tire casing and engage and fit snugly the innerrounded contour 26 thereof.

There are two supporting blocks and intermediate coil springs -ito each tire engaging metal p'late section, as clearly shown in'Fig'. 1', one supporting block being positioned very closeto one end of the section, as at 27, the other supporting block being positioned at about the center of its length as at 28.

The tire engaging plate sections overla'p each other, as shown at 29, Fig. 1, the plate ends, which carry supports, supporting the plate. ends of the adjoining plates which have no end supports.

By the foregoing disclosure and description itA will be clearly seen that l have provided a tire casing supporting means whereby the casingis supported at every point in itsfcireuinference and thereby lessen the possibility of cracking or bursting the casing. Also it will be readily understood that my invention can be applied to casings of varied sizes and structures and l do not limit myself to the type of tire casing here shown and described.`

Due to the springs 18 a very resilient tire supporting means is provided, the semi-circular shape of the blocks 14 and 20 and the tire-engaging metal plates 25, the casing is supported in its natural shape while the blocks receive a lateral support from the casing and to further safe-guard against any jar which might arise by the complete compression of the coil springs 1 have provided the fiat adjoining faces of both the upper and lower blocks with buii'ers 30.

In F ig. 4 of the drawings 1 have shown my tire supporting means being applied to a tire casing. A

My entire supporting element can be assembled before it is applied to a tire casing. When the apparatus is assembled, the tire is turned with its edges upward, and the tire engaging plate 25 is ypushed downward past the beads 6 of the tire casing, as shown inv Fig. et.' To facilitate the application of the invention, the blocks 14 and 2O are i turned upon their respective bolts until they are in a line with the wheel ring 8. After the platesv 25 have been pushed snugly against the inner face of the casing the blocks are turned transverse the wheel-ring and tire-casing and thc casing is then ready to be mounted, in the usual way, upon a rim. It will be understood that due to the fact that the blocks can be turned in a line with the wheel ring the supporting plates can be tilted and inserted into the tire casing in an edgwise manner until they are past the upper edges of the casing. 1f this were not possible it would be a very difficult 4 task to pass the plates through the narrow s ace between the edges oit' the tire casing. nce the plates are started into the tire they can be readily pushed into proper position. Having thus described my invention what l claim and desire to secure by Letters Patent is:
